UNTTE STATES PATENT OFFICE WILLIAM EDIVARD HARRIS, OF NEW YORK, N. Y.

MANUFACTURE OF PAINT FROM METALLIC LEAD.

SPECIFICATION forming part of Letters Patent No. 327,678, dated October6, 1885.

Application filed September 20, 1884.

T 0 aZZ whom it may concern.-

Be it known that I, WILLIAM E. HARRIS, of the city, county, and State ofNew York, have invented a new and Improved Process for Making MetallicPaint from Lead, of which the following is a full, clear, and exactdescription.

The object of this invention is to facilitate the making of paint frommetallic lead; and the invention consists in the process of making paintfrom lead by burning the metallic lead in contact with coke, coal, orcharcoal, and condensing the fumes, as will be hereinafter fullydescribed.

In carrying my invention into practical effeet a furnace is heated tothe temperature of about two thousand seven hundred degrees (2,700")Fahrenheit with coke, coal, or charcoal. Lead is then mixed with coke,coal, or charcoal in the proportions of about two tons of coke, coal, orcharcoal to one ton of lead, and the mixture is placed in the furnaceand burned. The lead will melt and run over, into, and through the coke,coal, or charcoal, and that which runs through is placed upon the SerialNo. 143,571. (No specimens.)

top of the mixture as fast as it runs through until it, and all the leadthat has lodged, has been vaporized. The fumes thus produced areconducted into and condensed in condensingehalnbers, and will be foundin a very finelydivlded condition, ready without grinding to be mixedwith oil for paint.

The action is as follows: The lead as it melts and runs over the coke,coal, or charcoal becomes oxidized,forming oxide of lead, which, comingin direct contact with the burning coke, coal, or charcoal, unites withits vapors, forming a fume that is condensed, and can be mixed with oiland used as a paint.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

The process of making paint from metallic lead, and which consists inburning lead in contact with coke, coal, or charcoal, and condensing thefumes, substantially as described.

\VILLIAM EDWARD HARRIS.
